1959-11-05 Pascual Perez w co 13 (15) Sadao Yaoita, Ogimachi Pool, Osaka, Japan - WORLD. Referee: Juan Notali. Having been outpointed by Yaoita (112) earlier in the year, Perez (107) proved to be too strong over the championship distance for his young challenger. Getting involved in a slugging match was not really to Yaoita’s advantage and it was a short right to the jaw that put him down in round 13 to be counted out with 55 seconds on the clock.

Perez’s next opponent would be Pone Kingpetch, who was highly rated by The Ring magazine after winning the vacant Orient title by beating Danny Kid and then successfully defending it against Hitoshi Misako before handing his belt back on 13 May 1958.
